Thanks guys. I have an E92 chassis 328xi with 17s and recall the fit being pretty tight. I know the newer generations have grown larger and there is an extra inch of rear leg room, but the wheels have also grown larger with the 19/20 inch combinations so I had minor concerns. Sounds like it should be a non-issue!
Now I just need to wrap up this refinance on my mortgage so I can go purchase an M4
